Bill -
I commend your efforts to get additional participation and I understand some being concerned about reactions in an open forum.
However, I've never considered any of these forums totally 'open'. As I go through the different members IDs there really is no information about anyone - you and George seem to be the only members actually using your names. I mean, who is 'dana'? or sparky, etc....an inspector in CGO, an electrician in Baltimore? Peoples identidies are completely masked in these forums so folks really do have an opportunity to speak their minds, opinions or mistakes without anyone else knowing who that individual really is.
But - all that said, if you go over to the IAEI site which is for members, there is very little participation compared to this site; you can go for days betweens postings.
